A gas turbine with low NOx emissions

NEDO  and Hitachi Ltd. (Tokyo, www.hitachi.com) have developed a new combustion technology that could reduce the emissions of oxides of nitrogen (NOx) to below 10 ppm without the addition of diluents. As part of the CCS-IGCC project (carbon capture and…

Bio-butanol scaleup moves ahead with trials

In April development tests, Cobalt Technologies (Cobalt; Mountain View, Calif; www.cobalttech.com) produced n -butanol at the fermentation scale of 100 m3 per run, demonstrating lower production cost than butanol produced from petroleum. This represents production that is a factor of…

Burner technology enables reduced NOx with short flame length

To comply with increasingly stringent regulations for NOx emissions, operators of industrial plants often turn to low-NOx burners to avoid much more costly post-combustion treatment approaches like selective catalytic reduction (SCR). But low-NOx burners are plagued by significant losses in…

These scavengers of water pollutants have a magnetic attraction

A process that uses magnetic nanoparticles, coated with a reactive material, to clean up contaminated water for human use is being developed at Stanford University (Stanford, Calif.; www.stanford.edu). The nanoscavengers, as they are called, are distributed in the water to…

Improved corrosion control in refinery steam systems

GE Power & Water (Trevose, Pa.; www.ge.com) has introduced a novel, dual-pronged approach to corrosion inhibition for boiler and steam-condensate systems in petroleum refineries. The technology is designed to prevent attack by acidic species on steam-system surfaces, providing reliability to…

Using low-temperature waste heat to make power

New Energy and Industrial Technology Development Organization (NEDO; Kawasaki City; www.nedo.go.jp) and Panasonic Corp. (Osaka, both Japan; panasonic.net) have begun testing a new type of power-generation system that uses anisotropic solid-state composites that produce an electrical current when a temperature…

A salty way to scrub CO2

Ammonia is a promising candidate for scrubbing carbon dioxide from fluegas, since each ammonia molecule can absorb one molecule of CO2, whereas amine absorbers require two molecules to do the same job. However, because ammonia is volatile, the fluegas must…

A bio-butadiene plant is planned

On the heels of its successful scaleup of bio-butanol, Cobalt is looking for pathways to use that molecule as a building block for other products. The company has announced plans to build the first bio-butadiene plant in Asia. Projected to…

Nanowires improve the properties of metal composites

Freestanding nanowires exhibit ultrahigh elastic-strain limits (of up to 7%) and yield strengths. However, it has been difficult to exploit their properties in bulk composites, due to the mismatch between the elasticity of the nanowires and the elasticity of the…
